Definitions

  • the present invention relates to a method for producing an optical waveguide ribbon from optical waveguides which are brought together next to one another in a plane and are subsequently fixed to one another by an adhesive in this association.
  • An optical fiber ribbon is a basic element of a cable. For example, 2 to 10 optical fibers are arranged in an optical fiber ribbon.
  • the invention is based on the object of specifying a method for producing an optical waveguide ribbon which results in a high packing density in the cable constructed from optical waveguide connectors. This object is achieved by a method with the characterizing part of claim 1.
  • FIG. 1 shows a device for producing an optical waveguide ribbon according to the invention.
  • 10 optical waveguides 1 are provided, which are processed to form an optical waveguide band.
  • These 10 optical fibers (fibers) 1 are fed from a fiber drain device 2 to a device 3 which brings the 10 optical fibers 1 into one plane and arranges them parallel to one another.
  • the device 3 is, for example, a slot nozzle which has a dimensioned slot corresponding to the number of 10 optical waveguides to be processed.
  • the optical waveguides 1 are fed to a spray device 4 after leaving the slot nozzle in a parallel arrangement and lying in one plane.
  • an adhesive is sprayed onto the optical waveguide 1.
  • the adhesive consists, for example, of a hot melt adhesive, which has the property that it cools immediately after being sprayed onto the optical waveguide and solidifies, so that it binds the optical waveguide.
  • the hot melt adhesive Before spraying, the hot melt adhesive is melted so that it is in the sprayable state.
  • the melted hot melt adhesive is sprayed onto the optical fibers by pressure using tempered compressed air.
  • the sprayed amount is so small that the thermal energy of the hot melt adhesive is quickly dissipated. This ensures that the hot melt adhesive solidifies very quickly.
  • FIG. 2 shows a section of an optical waveguide band 5 after being fixed by the adhesive.
  • the hot-melt adhesive does not have sufficient strength after being sprayed onto the optical waveguide in the solidified state, the required stability becomes of the optical waveguide band according to Figure 1 by applying a z. B. made of polyester film 6.
  • the carrier films 6 are first wetted by a hot melt adhesive by means of the device 7 and then rolled onto the optical waveguide band 5 by means of the rollers 8.
  • the adhesive is applied to the foils only immediately before the foils are rolled onto the optical fibers.
  • FIG. 1 also shows a take-off device 9 and a winding device 10.
  • FIG. 3 shows a section of an optical waveguide ribbon which has carrier films 6 on both sides to increase the mechanical stability.
